たことを特徴とする定電圧電源回路。 A driver transistor that has a differential configuration including a first transistor to which a reference voltage is applied to its base and a second transistor to which a voltage corresponding to a load voltage is applied to its base, and which is connected in series between a power supply and a load. In a constant voltage circuit whose base is connected to the collector of the first transistor, the collector current of the first transistor is detected, and the detected current is applied to the common emitter of the first and second transistors by a current mirror. A constant voltage power supply circuit characterized in that it is configured to supply a voltage to
